More details

Ok, here are the scans. The one on the left is one of the set of 8 sheets offered by the philatelic service. According to my source, the first day these were available was June 1, 2009.

The one on the right is one of the ones available at post offices around Israel.

While they are similar, they are not identical. The key difference to me is the label attached to the stamp. The ones from the philatelic service have the generic label, while the ones at the post office have different images. There are at least 5 labels for each stamp that you can find at the post office. The other differences are the text in the yellow box in the center, and trhe inclusion of a web address in the white section on the bottom of the philatelic service ones.

Below you can see the envelopes that these are sold in at the post office. There is no way to know what one you are buying until you open the package. It is more like collecting baseball cards in packs then stamps. Each package at the post office is NIS4.90, or about $1.25. Unfortunately, based on my experience at 1 post office, about 80% of the ones you buy are duplicates. Maybe the chances are better if you buy a few at a bunch of different post offices, but I didn't have the ability to test that out.
